Bless / Exp bars disappear at 1080p game resolution

I'm running Shaiya on a 24-inch monitor which has a native resolution of 1920x1080. I have been running the game at 1680x1050 and the UI displays normally, however when changing to 1920x1080 resolution (which otherwise looks much better and crisper) the Exp / Bless bar portion of the UI including shortcut buttons simply disappears.

I can understand this happening with resolutions of a different aspect ratio than my monitor (parts of the UI showing off-screen), but 1920x1080 is the native resolution of my monitor and yet this part of the UI vanishes.

Is Nexon aware of this, and do they plan to implement a fix? This is one of the most popular resolutions for PC gaming, surely they must recognize the importance of this resolution displaying correctly, especially since it is an option offered in the game settings.

Edit: I should add that the current target indicator is also absent under this resolution.
